Hi Daniel,

 When I make a transparent surface for a volume by pressing the volume 
dialog color button and making opacity 0.5 and then use color zone to 
color part of the surface (using a PDB model), the transparent part far 
from the zone remains transparent.  Also works if select the volume 
surface and use the Actions / Surface / Transparency menu then color 
zone.  What are the exact steps you use when it fails to preserve 
transparency?
